Jlastino you are my hero lol :)

jlastino · Answer

Given the center of the of the circle (h,k) and the radius, the equation is

(x-h)^2 + (y-k)^2 = r^2

so what's the equation? (I'm gonna go to an anime convention so i won't stay much long here haha)

anonymous · Answer

is 4 and -5 the h and k?

jlastino · Answer

yeah

anonymous · Answer

ok so (x-4)^2 +(y-5)=3^2

jlastino · Answer

hmm there's something wrong with (y-5)^2   k= -5 so y-(-5) would become...?

anonymous · Answer

positive 5

jlastino · Answer

so what's the right equation? :D

anonymous · Answer

(x-4)^2 +(y+5)=3^2

anonymous · Answer

^2 sorry

jlastino · Answer

oh ok just simplify 3^2 and that would be the correct answer

jlastino · Answer

(x-4)^2 + (y+5)^2 =9

anonymous · Answer

right sorry. um so thats the answer :)
